A company runs a web application on EC2 instances in an Auto Scaling group. During a flash sale, traffic spikes dramatically. The operations team wants the Auto Scaling group to automatically add more instances when CPU utilization exceeds 70% for 5 minutes, and remove instances when it drops below 30% for 15 minutes. What should the team configure?

Use AWS Systems Manager Automation to run a script that modifies the desired capacity of the Auto Scaling group based on CloudWatch alarms.

Create a simple scaling policy that adds one instance when CPU exceeds 70% and removes one instance when CPU drops below 30%.

Create a target tracking scaling policy based on average CPU utilization with a target value of 70%.

Create a step scaling policy with two steps: one to add instances when CPU is above 70% and one to remove instances when CPU is below 30%.

Which of the following is an example of modifying an infrastructure configuration in response to an operational event?

Creating a new IAM user for a developer

Changing an Auto Scaling group's minimum and maximum instance counts after a traffic spike

Running a read-only AWS Config query

Viewing CloudWatch logs to diagnose an issue
